Hi,

I'm getting some very strange problems with some C# code. We're running
an ASP.NET application on a local server in a DMZ. If I access it using
the internal address, the application works fine, every time. But, if I
access on it's public IP, from my office workstation, from home, over
the VPN, a test machine on ADSL, or whatever else you please, it fails.
But only about 60% of the time.

I have tried everything to pin this down. I'm fairly sure it's not the
software, because I've rolled back to earlier versions, installed the
same thing of different machines, etc. We've examined the network
interfaces (which seems to be the key to causing the problem) but we
just cannot find anything that apparently causes it.

If anyone has any ideas, I'd be extremely grateful. On the off chance I
find a solution, I'll post it here. No one else would seem to have had
the same error that I can find. The nearest is about user impersonation
through anonymous login, but I've covered that one already.

At the point at which it fails in my code, it is calling generated code
from a WSDL file to make a SOAP transaction against a web service...
Using Lutz Roeder's .Net Reflector, I'd say the framework is doing
something it's supposed to do:

(Top of the stack trace...)
if (!File.Exists(text2))
{
throw new InvalidOperationException(
SR.GetString("CompilerNotFound", new object[] { text2 })
);
}

But as the compiler _IS_ there, I don't see why it does this
specifically, and regularly from a particular entry point...

Any ideas world? Cheers,

mudge.

most likely you are using default serialization code and impersonation. the
first time you serialize, or deserialize an object, .net uses reflection to
determine the member to serizalize, generates code (so early binding instead
of late binding can be used), compile the code, and load the module.

this means the thread that first calls serialization must have the proper
permissions to the temp dirs used to compile (as only javascript supports in
memory compiles, all other compiler write to disk first).

you have three choices,

1) give everone permission to the temp folders (not the best)
2) before calling serialzation revert to the asp.net account, then restore
impersonation after serialzation.
3) do a dummy serialization of your objects in the application onload.

Hi Bruce,

Thanks for that. This does sort of make sense. But the one thing that
is still bugging me is why this doesn't consistently fail. From what
you say here, I would expect the system to fail each and every time,
whereas it has about a 40/60 successs/failure rate...

I'm afraid I've not had a chance to try out what you suggest yet, but I
will do as soon as I get a free moment.

Cheers,

mudge
